Organic Compounds and the Miracle of Smell and Taste

Neo-Darwian evolutionary theorists and human ethologists seem to ignore the fact that reproductive isolation is nutrient-dependent and controlled by the physiology of reproduction. …reproductive isolation may sometimes follow and at other times precede the adaptive divergence of gene pools of populations. — Dobzhansky (1972) Those who cite Dobzhansky’s (1973)  claim that Nothing in Biology Makes Any Sense Except in the Light of Evolution, have failed to explain why …the so-called alpha chains of hemoglobin have identical sequences of amino acids…

Natural cooperation and Evolution 2.0

More than 45,000 published journal articles indexed on PubMed already contained the term microRNA before evolutionary theorists declared the microRNAs were linked from their emergence to all biodiversity via mutations and evolution in: MicroRNA mechanisms of action: what have we learned from mice? Conclusion:  We speculate that miRNAs emerged during evolution to increase the complexity of gene regulation, thereby contributing to the diversity of organisms. See for comparison: ‘Natural cooperation’ is nutrient dependent and pheromone controlled See also: Evolution 2.0…

A two-faced protein enables RNA-mediated DNA repair (5)

The title of the article below about “gut bugs” attests to the fact that the popularity of neo-Darwinism is based on the lack of popularity for any alternative. For example, Schrodinger (1944) claimed: …in the case of higher animals we know the kind of orderliness they feed upon well enough, viz. the extremely well-ordered state of matter in more or less complicated organic compounds, which serve them as foodstuffs. After utilizing it they return it in a very much degraded…

A two-faced protein enables RNA-mediated DNA repair (3)

See: A two-faced protein enables RNA-mediated DNA repair (2) See: A two-faced protein enables RNA-mediated DNA repair My comment: Attempts to place what is currently known about the links from atoms to ecosystems back into the context of neo-Darwinian pseudoscientific nonsense have been doomed to fail ever since Dobzhansky (1973) wrote: Nothing in Biology Makes Any Sense Except in the Light of Evolution. He linked nutrient-dependent amino acid substitutions to cell type differentiation across species and also claimed “…the so-called…

Indeed, several candidate gene studies in humans reported that STR variations modulate gene expression19,33–37 and alternative splicing… Reported as:  Researchers find repetitive DNA provides a hidden layer of functional information Excerpt:  He is calling these variants eSTRs, or expression STRs, to note that they…

Teaching the biologically uninformed

Stark Reality by Todd I. Stark: Computer consultant, science writer, avid reader, martial arts enthusiast. My favorite discussion topics are cognitive neuroscience, psychology, biology, problem solving, human performance, and Microsoft SharePoint technologies. Fatness and Obesity: Framing the Problem Excerpt: …we have to understand what about our lives is most mismatched with our ability to regulate our energy storage. Is it the sorts of things we are eating? The activities we engage in? The nutritional quality available to us? The amount…

Energy expertise, evolution of yeasts, and better beer

Energy Expertise: Excerpt: Chris Hittinger studies the diversity and evolution of yeast carbon metabolism, which is controlled by a complex system of interacting genes that respond to different carbon sources and determine the organism’s energy-use strategy. By understanding how evolution has sculpted and rewired yeast gene networks to meet their different ecological needs, Hittinger hopes to better understand how to engineer complex biological systems to meet our energy needs. ​   My comment: Doxycycline induction appears to be used without…

Stress-perturbed mitochondrial dysfunction

Mitochondrial functions modulate neuroendocrine, metabolic, inflammatory, and transcriptional responses to acute psychological stress Excerpt: To visualize the stress-reactive profiles across genotypes, a heat map with hierarchical clustering of the mean relative difference “stress–resting” was generated, demonstrating that each mitochondrial defect induced a different amino acid response signature (Fig. 4F). In particular, the stress-reactive amino acid profile was most distinct in mice with the respiratory chain complex I ND6 defect. To determine which class of amino acids was most discriminatory between…

Xist-ing on planet Earth

Sex Differences in the Brain (revisited) A comment that was complementary led me to add this: Ideas about evolutionary processes that automagically led to sex differences in cell types can be dissmissed in the light of experimental evidence of biologically-based cause and effect. Since 1996, for example, serious scientists have known about the role of Xist in chromosome inactivation. See also, from 2015:An Xist-activating antisense RNA required for X-chromosome inactivation In our Hormones and Behavior review we (TB) wrote: “Genomic-imprinting…

Supercoiled DNA constrains virus-driven genomic entropy

1) Genes linked with malaria’s virulence shared by apes, humans and 2) Supercoiled DNA is far more dynamic than the ‘Watson-Crick’ double helix were reported today. One report (1) links viruses to the evolution of biodiversity in chimpanzees and humans compared to gorillas. The other report (2) links nutrient energy-dependent base pair changes to RNA-mediated amino acid substitutions and DNA repair. Both reports are linked to open access publications: See 1)  Ape parasite origins of human malaria virulence genes Excerpt:…
